The Losmandy G11 RA Extension Kit adds 1.5-inch to the RA body and raises the saddle plate by 0.6-inches on the Losmandy G11. This is done to make it far easier to perform a Meridian Flip with your mount without the motor getting in the way of the counterweight or scope arms.

Installing this kit will also make removing the DEC axis much easier, a boon when transporting the G11 and you need to break it into multiple pieces.
